If you live in the Houston area, you can now use your mobile phone to redeem coupons for JCPenney through a trial-partnership with Cellfire. You have to register with Cellfire in order to receive the promos via SMS or email, and if you register today you’ll receive a mysterious “$10 in$tant gift” [sic].

It’s bad enough when friends and acquaintances bombard you with text messages, but at least most humans can be reasoned with. Monica, on the other hand, says she’s being hassled by a robot who sends here 20 texts a day, and that Verizon has been slow to jump to her aid.

Online coupons still haven’t caught on, really, but 8coupons.com may be worth checking out if you want to give it a try in your own city. Instead of implementing some high-concept location aware thing, they let you browse the site for coupons that interest you. When you find one, you send it to your phone via text message. Obviously, if you hold your phone number dear to your heart, don’t bother; if you’re the brave type who doesn’t mind risking the personal data exposure, you might want to give it a shot.

Here’s an idea, don’t use your phone to send 300 texts a day at school. Not only will your parents not get a bill for $4,756.25, you won’t go from As and Bs to Fs and you also won’t get your phone smashed with a hammer.

Senators Olympia Snowe, R-Maine, and Bill Nelson, D-Florida, have introduced the m-SPAM Act, which would update the CAN-SPAM law to include text message spam. “The m-SPAM Act would explicitly bar marketers from sending text messages to any mobile number in the national Do-Not-Call registry maintained by the FTC,” reports InternetNews.

Subway has launched a pilot program called SubwayNow where New York City residents (Manhattan only at the moment, it looks like) can register to place pick-up orders via text message. According to IntoMobile, after registering with your address and providing payment info, which they keep on file, you set up a list of sandwich orders that are saved as a personal menu. When you’re ready to use the service, you text “menu” to the Subway shortcode, and Subway sends back your pre-set menu. Then you text back the menu item you want, and Subway responds with a pick-up time.

We got an email today from a Sprint representative addressing the confusion over just what “unlimited” means in their unlimited messaging package. If you recall, Erica says Sprint told her she would still be billed per message when sending pics or video, which runs contrary to the offer she signed up for. Now Sprint has officially responded that unlimited means no additional charges, and they’re investigating the matter. Below is their statement.

Sprint offers an “Everything Messaging Family” package that promises “unlimited nationwide, text, picture and video messaging to anyone on any network.” The catch? Unlimited seems to mean “you have the capability to send messages, but you’ll still have to pay for each message you send.” Erica has called in twice to clear up the mistake, but the CSRs are telling her it’s not a mistake. Oh. Well then, is it a lie?

AT&T spammed a “‘significant number’ of its 75 million customers” yesterday with text messages advertising the premiere of American Idol. AT&T also pissed off a significant number of its 75 million customers in the process, and the company’s justification for the blitz isn’t exactly making AT&T sound smart when it comes to understanding what qualifies as spam.

The national wireless carriers have responded to the Senate’s request for information on why its text-messaging fees have doubled over the past three years. Their collective response: they haven’t gotten more expensive, they’ve gotten cheaper—and your public suspicion of our business practices has led to lots of class action lawsuits!

Under the terms of a preliminary settlement agreement, [Timberland and e-commerce company GSI] will pay $7 million into a cash fund to reimburse those who received the messages, according to KamberEdelson LLC, one of the law firms that helped bring the suit.

Chelsea wants to know why she keeps receiving these cryptic text messages from 9099. The messages alternate between telling her new phantom services have been added to her account, and sending her an account PIN and security answer. We thought it was someone trying to gain access to her account, but the PIN and security answer aren’t hers, and the services never show up on her bill.
